I looked up the registry hack, it's not really what I want since I'm afraid it won't be supported in future versions. That sucks! It would be nice to sort my own libraries and create a cover for it instead of this file browsing madness.

if you drag other nki files into the directory structure of an existing library that is available in the libraries tab. the extra nkis will show up there. i have most of my samples in the kontakt 4 tab.
